Abstract The demand for high-quality faculty development in medical education is more acute than ever. Faculty developers’ responsibilities are growing exponentially as they are called upon to help medical faculty maintain expertise in an evolving array of content domains, curricular and assessment strategies, education technologies, and active learning methods. Faculty development has a long history of supporting medical education colleagues in times of change. More recently expectations for faculty developers are expanding due to (1) increasing enrollment of learners, (2) emphasis on learner-centered teaching practices and competency-based assessment methods, and (3) heightened accreditation standards for training faculty. Yet, faculty development in medical education lacks the conventional structures of a profession, such as an adopted set of competencies. In 2023, a series of sessions at regional, national, and international medical education conferences were held to generate ideas and collect examples of faculty developer competencies from over 100 stakeholders. More than 500 responses were gathered from prompts such as “What are the competencies faculty developers need?” and “What is one of the most valuable faculty developer competencies today?” This perspective offers both a rationale for establishing faculty development in medical education as a profession and a path forward through the provision and broad promotion of clearly defined core competencies. The competencies outlined are intended to help inform those entering or currently working in the profession, recruiters of faculty developers, medical education leaders, institutional partners, those conducting performance appraisals of faculty developers, and the broader medical education community. The aim of this work is to generate discussion among vested medical education and faculty development stakeholders who seek to provide structure, clarify roles, and further define medical education faculty development as a profession.

ABSTRACT Background Sentinel lymph node (SLN) biopsy is a critical staging tool in skin and soft tissue cancers. Although technetium lymphoscintigraphy is the most common adjunct, indocyanine green (ICG) demonstrates a promising alternative in pediatric, adolescent, and young adult (AYA) skin and soft tissue cancers. Methods and Objectives Evaluate the safety and efficacy of ICG in SLN biopsy (SLNB) in diverse pediatric and AYA solid cancers in a multi‐institutional environment. This is a prospective, observational study conducted at 13 member institutions in the Pediatric Surgical Oncology Research Collaborative between 2019 and 2023. Eligible patients underwent SLNB for primary or recurrent solid skin and soft tissue tumors. Peritumoral ICG was administered intraoperatively. Outcomes included SLN detection rates, histopathology of excised specimens, and surgeon‐reported assessment of utility. Safety was assessed through adverse event reporting. Results Forty SLNB procedures yielded 84 specimens: 13 melanoma (32.5%), 12 squamous cell carcinoma (30%), 11 non‐rhabdomyosarcoma soft tissue sarcoma (27.5%), two rhabdomyosarcoma (5%), one Ewing sarcoma (2.5%), and one malignant peripheral nerve sheath tumor (2.5%). Histologic evaluation identified 81 lymph nodes, 75 benign (89.3%) and six malignant (7.1%); three specimens were adipose tissue (3.6%). Of 81 lymph nodes, 76% were ICG‐positive. ICG had a sensitivity of 79.5%, a specificity of 33%, and a positive predictive value of 96%. All malignant nodes were ICG‐avid. There were no adverse reactions to ICG at 30 days. Conclusions ICG is a safe and effective adjunct for SLNB in pediatric and AYA soft tissue and skin malignancies.

Abstract Purpose Clinician educators are essential to the academic medicine workforce, yet understanding how they assess their own teaching competencies is limited. The Clinical Educator Milestones (CEMs) guide growth across key educator domains, but their use and perceived relevance remain underexplored. This study aims to (1) evaluate clinician educators’ self-reported performance on the CEMs; (2) examine differences by career level, specialty, and experience; and (3) inform faculty development efforts through a clearer understanding of educators’ perceived strengths and gaps. Method Clinician educators from 9 US academic institutions completed a self-assessment rating their performance across 4 universal pillars and 11 educational theory and practice competencies on a 1- (novice) to 5- (expert) point scale in 0.5-point increments from August to November 2024. Descriptive statistics and mean difference tests were used to analyze variation across demographic and professional characteristics. Results A total of 484 responses to at least 1 CEM were received. Respondents rated themselves highest in commitment to professional responsibilities (mean [SD], 4.30 [0.68]), teaching and facilitating learning (mean [SD], 3.96 [0.74]), and professionalism (mean [SD], 3.93 [0.73]) and lowest in medical education scholarship (mean [SD], 3.11 [1.15]), program evaluation (mean [SD], 3.33 [1.03]), and the science of learning (mean [SD], 3.43 [1.10]). Statistically significant group differences were found by years of posttraining clinical experience (F2,413 = 16.87, P < .001, η2 = .076), years of teaching experience (F2,433 = 20.87, P < .001, η2 = .088), and academic rank (F2,403 = 13.96, P < .001, η2 = .065). Conclusions This study identifies key trends in self-perceived strengths and needs among clinician educators and highlights the limited awareness of the CEM framework. As institutions aim to build effective educator development systems, the CEMs can serve as a useful structure for tailoring support to individuals and identifying institutional needs.

Context: Testosterone is a steroid hormone produced primarily in the testes in men and ovaries in women, playing crucial roles in androgenic, anabolic, and psychological functions, including muscle growth, bone formation, erythropoiesis, risk-taking, and aggression, making it important for athletes. Sports performance is linked closely to testosterone level, prompting athletes to explore legal and illegal ways to boost testosterone. This review examines testosterone physiology and legal strategies for optimizing testosterone levels in athletes, as well as their practical applications. Evidence Acquisition: Database search. Study Design: Narrative review. Level of Evidence: Level 5. Results: Maintaining healthy testosterone levels requires energy balance and optimal nutrition with adequate macronutrients and micronutrients, especially for athletes prone to dieting and food restriction. Testosterone boosters are marketed widely but lack strong evidence for efficacy and may pose risks. While some substances show promise, further research is needed. Sleep is critical as testosterone secretion is linked to the rapid eye movement phase, highlighting the need for proper sleep hygiene and addressing sleep disorders. Moderate-to-high intensity free-weight resistance exercises are most effective for increasing testosterone, while the effects of sexual activity remain unclear. Endocrine-disrupting chemicals can lower testosterone levels and should be avoided. While cold-water immersion may decrease testosterone, sauna bathing appears to be neutral. Radiofrequency electromagnetic radiation from modern electronic devices may harm the hypothalamic-pituitary-gonadal axis, warranting limited use. Over-the-counter analgesics, such as nonsteroidal anti-inflammatory drugs and acetaminophen, may decrease testosterone levels, suggesting cautious use. Seasonal changes in testosterone levels require further study. Testosterone-optimizing strategies excluding banned substances may aid in treating functional low testosterone or reducing harm in anabolic-androgenic steroid users. Conclusion: Educating athletes on safe and effective strategies to increase testosterone is crucial, with ongoing research needed to explore additional methods. Strength-of-Recommendation Taxonomy: B.

Abstract Background & Aims Central reading of endoscopy and histopathology is the current standard for disease activity assessment in inflammatory bowel disease (IBD) clinical trials but is limited by interreader and intrareader variability, operational delays, and cost. Artificial intelligence (AI) and machine learning (ML) offer the potential to improve accuracy, efficiency, and reproducibility. The International Organization for the Study of IBD (IOIBD) developed consensus statements on AI/ML use for endoscopic and histologic endpoint assessment in IBD trials. Methods As part of the IOIBD endpoints cluster initiative, a narrative, evidence-informed review with literature searches of Medline and Embase (January 2018-February 2025) identified studies applying AI/ML to endoscopy or histology in IBD. Relevant evidence informed 36 survey statements formulated by a steering committee. Seventy-two IOIBD members were invited to vote online; consensus required ≥80% agreement (score: 7-10 on a 10-point scale). Results Forty-five members completed the survey. Consensus was reached for 28 statements related to endoscopy, pathology, and trial design. Experts agreed that AI-based central reading could improve diagnostic accuracy, expedite processes, reduce costs, and enhance reproducibility. Combining human and AI assessments was favored over AI replacement. The key limitations identified included insufficient validation, generalizability concerns, and dependence on human-annotated training datasets. Conclusions This IOIBD consensus supports the integration of AI/ML into central reading for IBD clinical trials to improve objectivity, efficiency, and consistency, while maintaining human oversight. Further research should address validation, regulatory frameworks, and multimodal integration to enable broader adoption in both trials and clinical practice.

Abstract The cortical asymmetry index evaluates the cortical thickness asymmetry between hemispheres. We investigated cortical asymmetry index in asymptomatic and symptomatic mutation carriers of autosomal dominant Alzheimer’s disease to explore the brain asymmetry within the Alzheimer’s disease continuum. Sixty baseline T1-weighted MRI scans were obtained from the Clinic Barcelona cohort. Baseline and longitudinal MRI data from 564 participants within the dominantly inherited Alzheimer network observational study were used as an independent, confirmatory cohort. Cerebrospinal fluid and plasma neurofilament light chain levels were included when available. Cortical thickness was calculated using Freesurfer and cortical asymmetry index was calculated via an open-source pipeline. Cross-sectional analyses examined cortical asymmetry index differences based on clinical classification and APOE ε4 status, adjusting for age, sex and estimated years from onset, while correlations were assessed with age, estimated years from onset, mini-mental state examination scores, and neurofilament light. Longitudinal cortical asymmetry index evolution was modelled using generalized additive models in the dominantly inherited Alzheimer network observational study cohort, incorporating age, sex, and the interaction between group and estimated years from onset. The cortical asymmetry index successfully distinguished asymptomatic mutation carrier and symptomatic mutation carriers from healthy controls in the Clinic Barcelona cohort and symptomatic mutation carriers from controls in dominantly inherited Alzheimer network observational study. Higher cortical asymmetry index in mutation carriers (asymptomatic mutation carrier and symptomatic mutation carriers combined) and in symptomatic mutation carriers were associated with higher plasma neurofilament light levels, a closer proximity to symptom onset, and lower mini-mental state examination in the Clinic Barcelona cohort. In the dominantly inherited Alzheimer network observational study cohort, mutation carriers exhibited increased cortical asymmetry index compared to controls and correlated with elevated neurofilament light (plasma and Cerebrospinal fluid), lower mini-mental state examination, and a closer proximity to symptom onset. APOE3/3 carriers showed greater asymmetry than other APOE genotypes and significant cortical asymmetry index differences between asymptomatic mutation carrier and symptomatic mutation carriers. Longitudinally, cortical asymmetry index increased over time significantly in symptomatic mutation carriers. These findings underscore brain asymmetry as a potential biomarker for early Alzheimer’s disease progression in autosomal dominant Alzheimer’s disease, with implications for detection and monitoring tracking disease-related neuroanatomical changes.

Abstract Histiocytic neoplasms with xanthogranulomatous morphology encompass a continuum of disorders—from isolated cutaneous juvenile xanthogranuloma (JXG) or adult xanthogranuloma (AXG) to the multisystem Erdheim-Chester disease (ECD)—that share overlapping histopathologic and molecular features. In this article, we (1) define the spectrum of xanthogranuloma lesions, highlighting morphologic and immunohistochemical commonalities; (2) examine the clinical and radiographic criteria that distinguish localized juvenile xanthogranuloma/adult xanthogranuloma from classical Erdheim-Chester disease and related entities; (3) review the latest insights into MAPK pathway alterations that blur traditional diagnostic boundaries; and (4) outline contemporary management strategies, including approaches to staging “occult” disease, patient selection for BRAF and MEK inhibitors, and the role of other targeted and nontargeted agents. Readers will gain practical frameworks for recognizing early or atypical presentations, integrating molecular testing into routine practice, and optimizing personalized therapy across the xanthogranuloma family.
